# BitBop-91M

Latent-free **ternary** language model trained with **BitBop** (weights in {-1,0,+1}, no latent
full-precision copy; only a bf16 flip momentum as optimiser state). Trained on a single RTX 3060 (6 GB).

- Data: TinyStories (~90M tokens)
- BLiMP macro-accuracy (own harness): **59.07**
- Arch: d768, 12 layers, 1 full-attention layer(s) + sliding-window, NoPE, tied interface.
- Recipe: per-row RMS flip, tau=(2.0,2.75); see the code/report at github.com/ValerioDolci/bitbop.

Proof of concept; budget-scoped (not SOTA, no speed claim). Load with the `bitbop` package (config.json + model.pt + tokenizer.json).
